A former Mt. Juliet High School teacher and wrestling coach pleaded guilty Tuesday to three counts of sexual battery by an authority figure and one count of soliciting sexual exploitation of a minor after being charged with sex crimes for inappropriate conduct toward a student.

Darin Plumlee, 47, was arrested in May 2017 after being indicted by a grand jury on three counts of statutory rape by an authority figure, three counts of sexual battery by an authority figure, unlawful sexual contact, and sexual exploitation of a minor, according to the Wilson County Sheriff's Office.

Sentencing is scheduled for April 17, but the plea agreement includes a six-year term on the sexual battery by an authority figure charges to run concurrently.

Criminal Court Judge John Wootten Jr., will decide the manner of service on the six-year term.

The judge will also decide on length and manner of the term on the sexual exploitation of a minor charge and whether it will be served consecutively or concurrently with the three counts of sexual battery by an authority figure charges.

Wilson County Schools received a phone tip on April 13, 2017, alleging the inappropriate conduct by Plumlee, according to the district.

According to prosecutors, Plumlee at first denied allegations of inappropriate conduct toward a student. However, Plumlee then initiated another interview days later with police and came forward with the admission of inappropriate behavior toward the student.

Plumlee resigned from the district after the allegations came forward. Plumlee stated to the judge in court that he accepted “responsibility for my actions.”

"He wanted to accept responsibility for all his actions and that's what he did," Plumlee's attorney Frank Lannom said.

Wilson County Schools had no other complaints about Plumlee that resembled the allegations he was charged with, the district stated after his arrest.

Plumlee had been at Mt. Juliet High since 2014 and worked as a teacher. Plumlee was a teacher and wrestling coach at Lebanon High from 2000 to 2011, when he resigned to work for another district, according to his personnel file.
